Erysimum plant named 'honeyberry'

Abstract

A new and distinct variety of ERYSIMUM plant named ‘HONEYBERRY’ which is characterized by compact freely-branching habit, variegated foliage, crimson and mauve sweetly scented flowers which are produced from spring until early summer. In combination these traits set ‘HONEYBERRY’ apart from all other existing varieties of ERYSIMUM known to the inventor.

Description

GENUS AND SPECIES

GENUS: ERYSIMUM

Species: ×hybrida

DENOMINATION

Denomination: ‘HONEYBERRY’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Erysimum, also commonly known as perennial wallflower, which is grown as an ornamental for use in planted containers and in the garden and landscape. The new cultivar is known botanically as Erysimum xhybrida, and will be referred to hereinafter by the cultivar name ‘HONEYBERRY’.

‘HONEYBERRY’ arose and was discovered by the inventor in 2009 as a naturally occurring variegated branch sport on a single plant in a crop of Erysimum plants which had been raised from seed at the inventor's nursery in Walberton, West Sussex, United Kingdom. The seeds were unnamed and all plants raised from the seed were non-variegated, except for the single plant with the observed variegated branch sport.

‘HONEYBERRY’ was first asexually propagated by the inventor in 2010 in Walberton, West Sussex, England. Asexual propagation was accomplished using softwood cuttings. Since that time, under careful observation, the distinguishing characteristics of ‘HONEYBERRY’ have been determined stable and uniform, and to reproduce true to type in successive generations of asexual propagation.

SUMMARY OF THE INVENTION

The distinguishing characteristics of ‘HONEYBERRY’ are as follows: In combination these traits set ‘HONEYBERRY’ apart from all other existing varieties of Erysimum known to the inventor. ‘HONEYBERRY’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions.

1. ‘HONEYBERRY’ is hardy and perennial in USDA Zone 7 and warmer.

2. The growth habit of ‘HONEYBERRY’ is compact and freely-branching.

3. The foliage of ‘HONEYBERRY’ is variegated, consisting of bright yellow colored margins on gray-green leaves.

4. The buds and opening flowers of ‘HONEYBERRY’ are crimson in color.

5. The fully open flowers of ‘HONEYBERRY’ are light mauve in color.

6. ‘HONEYBERRY’ blooms from spring until early summer.

7. ‘HONEYBERRY’ achieves a height of 30 cm and a spread of 20 cm in the first year of growth.

8. ‘HONEYBERRY’ achieves a height of 30 cm-40 cm and a spread of 30 cm-40 cm when mature and established as a perennial.

9. ‘HONEYBERRY’ grows well in full sun to part shade, in fertile well-drained soil.

COMPARISON WITH KNOWN VARIETY

The only other cultivar of variegated Erysimum known to the inventor is the variety ‘WALFRASTAR’ (U.S. Plant Pat. No. 23,101). ‘HONEYBERRY’ and ‘WALFRASTAR’ may be distinguished by flower color. Whereas the flowers of ‘WALFRASTAR’ are yellow in color, the flowers of ‘HONEYBERRY’ are crimson in color when opening, becoming light mauve when fully expanded.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of ‘HONEYBERRY’ showing the colors of its foliage and flowers as true as it is reasonably possible to obtain in colored reproductions of this type. Both drawings have been made from a one year old plant.

FIG. 1 depicts a whole plant of ‘HONEYBERRY’ at time of first flowering, in the spring. The illustrated plant has been grown in a 1 liter container in a frost-free greenhouse at the inventor's nursery in Walberton, West Sussex, England.

FIG. 2 depicts a close-up view of the inflorescence of ‘HONEYBERRY’ and depicts the crimson buds and the flowers which are crimson when opening, becoming light mauve when fully open.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of ‘HONEYBERRY’ as grown in a one liter container in a frost-free greenhouse in West Sussex, United Kingdom. The color determinations are in accordance with the 2007 edition of the Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used. Growing conditions are similar to those of other Erysimum.
